[Varicosis-Current treatment concepts]. / Varikosis ­ aktuelle Therapiekonzepte.

Varicosis is a chronic progressive disease characterized by varicose veins of the lower extremities. Pain, swelling and heaviness of the legs are typical symptoms. These symptoms are caused by a pathological venous reflux, arising from a weakness of the vein wall and progressive venous insufficiency. The indications for invasive surgery are the symptomatic clinical, etiological, anatomical, pathophysiological (CEAP) stages C2s-C6. Compression therapy and venoactive drugs can be recommended for conservative therapy. When it comes to surgical treatment conventional open vein surgery is associated with the best long-term results. Endovenous thermal ablation is associated with few postoperative complications and favors earlier mobilization of the patient. Sclerotherapy has become established with good clinical results for the ablation of reticular and telangiectatic veins, for recurrences and complicated vein anatomy.

Radiofrequency ablation for the treatment of great saphenous venous insufficiency using a newly developed VENISTAR catheter: A preliminary study.

OBJECTIVES: This study was aimed to assess the preliminary outcomes of radiofrequency ablation (RFA) using a newly developed catheter (VENISTAR) for the treatment of incompetent great saphenous veins (GSVs). METHODS: In this prospective observational study, endovenous RFA using a VENISTAR catheter was performed on 16 saphenous veins in 12 patients between August and November 2019. Patients' pre- and post-procedural data were recorded. Doppler ultrasound imaging and clinical evaluation were performed at 1 week and 1, 3, and 6 months to determine the efficacy and safety of the treatment. RESULTS: Technical success and complete closure of the targeted GSVs immediately after the procedure were observed in all 16 limbs (100%). However, one patient (one limb) was found to have partial occlusion without significant reflux after 1 week of follow-up. Kaplan-Meier analysis yielded a complete occlusion rate of 93% at 6 months of follow-up. The Venous Clinical Severity Scores at the time of all follow-up were significantly lower than those at baseline (3.3 ± 1.1 at baseline to 0.6 ± 0.6, 0.3 ± 0.6, 0.1 ± 0.4, and 0.2 ± 0.4 at 1 week and 1, 3, and 6 months, respectively) (p < .001). Mild post-procedural pain was noted in 7 and 4 limbs at 1 week and 1 month, respectively. Grade 1 ecchymosis over the ablated segment was noted in 5 (35.7%) of 14 limbs at 1-week follow-up. CONCLUSIONS: Endovenous treatment of GSV insufficiency using a new VENISTAR radiofrequency catheter has been shown to be feasible, effective, and safe throughout the 6-month follow-up.

The anterior saphenous vein. Part 4. Clinical and technical considerations in treatment. Endorsed by the American Vein and Lymphatic Society, the American Venous Forum, and the International Union of Phlebology.

BACKGROUND: The decision to treat a refluxing anterior saphenous vein (ASV) should be a clinical decision based on the assessment on the ASV's contribution to patient's signs and symptoms. Once the decision to treat has been made, there are anatomic, clinical, and technical considerations in treatment planning. METHODS: Clinical scenarios were discussed by a panel of experts and common anatomic, clinical, and technical considerations were identified. RESULTS: There are unique clinical considerations such as whether both the great saphenous vein (GSV) and ASV should be concomitantly treated, if a normal ASV should be treated when treating a refluxing GSV and when and how to treat the associated tributary varicose tributaries. Being aware of the anatomic, clinical, and technical considerations allows development of a treatment plan that optimizes long-term outcomes in patients with ASV reflux. CONCLUSIONS: Ultimately the treatment plan should be tailored to address these types of variables in a patient-centered discussion.

The anterior saphenous vein. Part 3. Systematic review of the literature and payor coverage policies. Endorsed by the American Vein and Lymphatic Society, the American Venous Forum, and the International Union of Phlebology.

OBJECTIVE: The objective of this study is to systemically review the literature on Anterior Saphenous Vein (ASV) reflux treatment and insurance impediments to treatment coverage. METHODS: A literature search was performed using a PRISMA framework. In addition, a cross-sectional analysis of insurance policies for ASV treatment was evaluated. RESULTS: Published evidence and treatment considerations in the literature for ASV treatment are discussed. In 155 of 226 (68.6%) insurance policies reviewed coverage of ASV ablation was allowed while 62/226 (27.4%) did not specify coverage and 9/226 (4.0%) specified ASV treatment was not covered. Of the 155 that provide ASV coverage, 98 (62.2%) provide coverage with criteria such as requiring prior treatment of the great saphenous vein. CONCLUSIONS: Vein treatment experts should continue to advocate to insurance carriers to update their varicose vein treatment policies to reflect the substantial clinical evidence so that patients with ASV reflux can be appropriately treated.

Differences in risk profile associated with varicose veins and chronic venous insufficiency - results from the Bonn Vein Study 1.

Background: The aim of this publication is to demonstrate similarities and differences in the association of risk factors with the prevalence of different manifestations of chronic venous disease (CVD), like varicose veins (VV), venous oedema (C3) and severe chronic venous insufficiency (CVI) in the population-based cross-sectional Bonn Vein Study 1 (BVS). Patients and methods: In the BVS 1 between 13.11.2000 and 15.3.2002, 3.072 participants, 1350 men and 1722 women, from a simple random sample of the general population of the city of Bonn and two rural townships aged 18-79 years were included. The overall response proportion was 59%. All participants answered a standardized questionnaire including information about socio-economic data, lifestyle, physical activity, medical history, and quality of life. Venous investigations were performed clinically and by a standardized duplex examination by trained investigators. The CEAP classification in the version of 1996 was used to classify the findings. Logistic regression models were performed for the association of possible risk factors with VV, venous edema (C3) and severe CVI (C4-C6). The predictive risk (PR) describes the association of the diseases and the possible influencing factors. Results: VV, venous oedema (C3) and severe CVI (C4-C6) have common risk factors like higher age, number of pregnancies, family history of VV and overweight or obesity. Female gender is significantly associated with VV and C3 but not with severe CVI (C4-C6). High blood pressure and urban living are only associated with C3 and C4-C6 disease whereas prolonged sitting is associated with C3 and lower social class with C4-C6 exclusively. Discussion: In many epidemiological studies risk factors were associated with chronic venous disorders in general. Our data show that VV, venous edema and severe CVI may have different risk profiles. Venous edema is more often associated with arterial hypertension and sedentary lifestyle whereas lower social class seems to be a risk factor for severe CVI including venous ulcers. Conclusions: The differences in the association of risk factors to VV, venous edema and severe CVI should be considered if prevention and treatment of chronic venous diseases are planned. As examples, compression stockings could be proposed in sitting profession to prevent oedema, VV patients with risk factors like obesity might benefit from early treatment for VV and obesity. More longitudinal evaluation of risk factors is necessary to evaluate the true risk profile of CVD.

Bacterial Species Involved in Venous Leg Ulcer Infections and Their Sensitivity to Antibiotherapy-An Alarm Signal Regarding the Seriousness of Chronic Venous Insufficiency C6 Stage and Its Need for Prompt Treatment.

BACKGROUND: Venous leg ulcers (VLUs) are a common chronic wound condition susceptible to infection by various bacterial species. Understanding bacterial presence and antibiotic sensitivity is crucial for effective treatment. Methodsː Medical records of 60 patients diagnosed with the C6 chronic venous insufficiency stage were analyzed retrospectively. The patients were divided into an active recurrent VLU group (33 cases) and a first-onset active VLU group (27 cases). Bacterial identification, antibiotic sensitivity, and laboratory markers were assessed. Resultsː Pseudomonas aeruginosa was the most prevalent bacterial species in both the study (72.72%) and control (37.03%) groups, along with other common bacteria such as Proteus mirabilis, Enterococcus sp., Staphylococcus aureus, Acinetobacter baumannii, Klebsiella spp., and Escherichia coli. Furthermore, uncommon bacteria, including Providencia rettgeri, Group B Streptococcus, and Salmonella Paratyphi B, and a fungal infection with Candida albicans, were identified only in the study group, while Morganella morganii was found exclusively in the control group. Pseudomonas aeruginosa showed significant sensitivity to several antibiotics, particularly Amikacin and Meropenem. Nonspecific laboratory markers, such as CRP, fibrinogen, ESR, WBC, CK, neutrophils, and lymphocytes, revealed statistically significant differences between groups, indicating their potential as biomarkers for monitoring recurrent VLUs. Conclusionsː These results highlight the need for comprehensive diagnostic approaches to effectively manage VLU infections and improve patient outcomes. Further research is warranted to explore factors influencing the presence of uncommon bacteria and to develop targeted interventions for VLU management.

Effectiveness of herbal drug Terminalia Arjuna in chronic venous insufficiency - A prospective observational study.

INTRODUCTION: Chronic venous insufficiency (CVI) manifests in various clinical presentations ranging from asymptomatic but cosmetic problems to severe symptoms, such as lower limb edema, skin trophic changes, and ulceration. CVI substantially affects the quality of life and work productivity of the patients. Ayurveda, an ancient traditional medicine in India, evaluates the various pathological stages of CVI with a wide range of pathological conditions such as Siragranthi (venous abnormalities), Raktavaritavata (disorders of vata occluded by rakta ∼ blood), ApanaVaigunya (vitiated apanavayu), Arsha (hemorrhoids), VataRakta (rheumatism due to rakta), Kushtha (integumentary disease) and Dushta Vrana (putrefied wound) depending upon the presentations of the patient. Ayurvedic texts mention Terminalia arjuna as a potential herb for treating various conditions related to the circulatory system. The drug is an effective anti-inflammatory, anti-oxidant, and anti-hypertensive and has a definite role in improving cardiovascular hemodynamics and wound healing. These attributes suggest that the potential of Terminalia arjuna needs to be explored as a promising venoactive drug. METHODS: This prospective observational study included 25 patients (31 limbs) with CVI who were treated with Tab Terminalia arjuna (Bark extract of Terminalia arjuna in a dose of 500 mg, given twice a day) and were observed on two visits on day 30 and day 90. Follow-up was carried out for three months to evaluate post-treatment complications or adverse effects. The clinical outcome assessment was done using Venous Clinical Severity Score (VCSS), and clinical grading was performed using clinical classification (C0 - C6) of CEAP (Clinical-Etiology-Anatomy-Pathophysiology) classification. RESULTS: The median VCSS score (of both limbs) during the third visit was comparatively lower than the first, with a statistically significant improvement at 0.05 level. Further, there was a substantial positive improvement in the clinical classification of CEAP among the patients in pre and post treatment phase. CONCLUSION: The prospective observational study shows that Tab Terminalia arjuna is safe and effective in CVI, reducing the symptoms like pain, edema, inflammation, pigmentation, induration and also expediting ulcer healing.

Investigating low rates of compliance to graduated compression therapy for chronic venous insufficiency: A systematic review.

Chronic venous insufficiency (CVI) is a chronic lower limb progressive disorder with significant burden. Graduated compression therapy is the gold-standard treatment, but its underutilisation, as indicated in recent literature, may be contributing to the growing burden of CVI. The aim of this systematic review is to determine the reasons for poor compliance in patients who are prescribed graduated compression therapy in the management of chronic venous insufficiency. A systematic review of the literature was conducted to identify the reasons for non-compliance in wearing graduated compression therapy in the management of chronic venous insufficiency. The keyword search was conducted through Medline, PubMed, CINAHL, Cochrane library, AMED, and Embase databases from 2000 to April 2023. Qualitative and quantitative studies were included with no study design or language limits imposed on the search. The study populations were restricted to adults aged over 18 years, diagnosed with chronic venous insufficiency. Of the 856 studies found, 80 full-text articles were reviewed, with 14 being eligible for the review. Due to the variability in study designs, the results were summarised rather than subjected to meta-analysis. There are five main overarching themes for non-compliance, which are physical limitations, health literacy, discomfort, financial issues, and psychosocial issues with emerging sub-themes. Graduated compression therapy has the potential to reduce the burden of chronic venous insufficiency if patients are more compliant with their prescription.

The anterior saphenous vein. Part 3. Systematic review of the literature and payor coverage policies. Endorsed by the American Vein and Lymphatic Society, the American Venous Forum and the International Union of Phlebology.

OBJECTIVE: The objective of this study is to systemically review the literature on Anterior Saphenous Vein (ASV) reflux treatment and insurance impediments to treatment coverage. METHODS: A literature search was performed using a PRISMA framework. In addition, a cross-sectional analysis of insurance policies for ASV treatment was evaluated. RESULTS: Published evidence and treatment considerations in the literature for ASV treatment are discussed. In 155 of 226 (68.6%) insurance policies reviewed coverage of ASV ablation was allowed while 62/226 (27.4%) did not specify coverage and 9/226 (4.0%) specified ASV treatment was not covered. Of the 155 that provide ASV coverage, 98 (62.2%) provide coverage with criteria such as requiring prior treatment of the great saphenous vein. CONCLUSIONS: Vein treatment experts should continue to advocate to insurance carriers to update their varicose vein treatment policies to reflect the substantial clinical evidence so that patients with ASV reflux can be appropriately treated.

Plethysmography: A game changer for chronic venous insufficiency diagnosis, treatment, and follow-up.

OBJECTIVE: Chronic Venous Insufficiency (CVI) presents a various clinical symptoms and treatment options. Although it is generally known which treatment option is more appropriate in which situations in CVI, it is even more difficult to find the right option in some uncertain situations. In this study, we aimed to evaluate the potential contribution of Digital Photoplethysmography (D-PPG) in the diagnosis of CVI and especially in the selection of treatment options. PATIENTS AND METHOD: This retrospective study was conducted at Bursa Heart and Arrhythmia Hospital, involving 721 consecutive patients diagnosed with CVI and with Endovenous Laser Ablation (EVLA) indication. The patients were divided into 2 groups according to the extent of the failure in Doppler USG. In Group 1, the insufficiency ended above the knee, and in Group 2, the insufficiency progressed to below the knee. Patients were evaluated based on anamnesis, physical examination, Doppler USG, and D-PPG. Clinical classification, Venous Clinic Severity Score (VCSS), Quality of Life (QoL) assessment, venous pump capacity (VPC), and venous refill time (VRT) were measured. RESULTS: The study included 263 male and 458 female patients with a mean age of 52.37 ± 12.26 years. Significant differences were observed between Group 1 (above knee reflux) and Group 2 (below knee reflux) patients in terms of VCSS, QoL, VPC, and VRT values. The mean values of VCSS, patient complaints, VPC, and VRT were higher in Group 2 patients. Similar findings were observed within the CEAP 2 subgroup. CONCLUSION: D-PPG shows potential as a valuable tool in the diagnosis and treatment of CVI. By providing information about venous hemodynamics and volume changes, it can assist in optimizing treatment decisions, including saphenous vein preservation. Combining D-PPG with Doppler USG may improve the comprehensive assessment of CVI and change the treatment option, especially for CEAP 2 patients. More research is needed to confirm these findings and explore wider applications of plethysmographic methods in the management of CVI.

Valvar bypass surgery to ameliorate persistent lower limb edema caused by post-thrombotic syndrome: a case report and literature review.

Obstruction and/or reflux compromise during venous emptying can facilitate different pathophysiologies in chronic venous insufficiency (CVI). We present a patient with persistent lower limb CVI edema caused by post-thrombotic syndrome (PTS), who responded well to femoral vein valve therapy via axillary vein bypass after unsuccessful valvuloplasty, and led a normal life. During a 12 month observation period, bridging vessels completely restored original anatomical structures. In a literature study, no similar surgeries were reported, but we show that this operation may be feasible in selected patients.

Factors Influencing Venous Remodeling in the Development of Varicose Veins of the Lower Limbs.

One of the early symptoms of chronic venous disease (CVD) is varicose veins (VV) of the lower limbs. There are many etiological environmental factors influencing the development of chronic venous insufficiency (CVI), although genetic factors and family history of the disease play a key role. All these factors induce changes in the hemodynamic in the venous system of the lower limbs leading to blood stasis, hypoxia, inflammation, oxidative stress, proteolytic activity of matrix metalloproteinases (MMPs), changes in microcirculation and, consequently, the remodeling of the venous wall. The aim of this review is to present current knowledge on CVD, including the pathophysiology and mechanisms related to vein wall remodeling. Particular emphasis has been placed on describing the role of inflammation and oxidative stress and the involvement of extracellular hemoglobin as pathogenetic factors of VV. Additionally, active substances used in the treatment of VV were discussed.

Efficacy and safety of crisaborole ointment, 2%, in participants aged ≥45 years with stasis dermatitis: Results from a fully decentralized, randomized, proof-of-concept phase 2a study.

BACKGROUND: Crisaborole ointment, 2%, is a nonsteroidal topical phosphodiesterase 4 inhibitor approved for the treatment of mild-to-moderate atopic dermatitis. OBJECTIVE: To evaluate the efficacy and safety of crisaborole in stasis dermatitis (SD). METHODS: In this randomized, double-blind, vehicle-controlled, decentralized phase 2a study (NCT04091087), 65 participants aged ≥45 years with SD without active ulceration received crisaborole or vehicle (1:1) twice-daily for 6 weeks. The primary end point was percentage change from baseline in total sign score at week 6 based on in-person assessment. RESULTS: Crisaborole-treated participants had significantly reduced total sign score from baseline versus vehicle based on in-person (nondermatologist) assessment (-32.4% vs -18.1%, P = .0299) and central reader (dermatologists) assessment of photographs (-52.5% vs -10.3%, P = .0004). Efficacy according to success and improvement per Investigator's Global Assessment score and lesional percentage body surface area reached statistical significance based on central reader but not in-person assessments. Skin and subcutaneous tissue disorders were common all-causality treatment-emergent adverse events with crisaborole. LIMITATIONS: Small sample size and short treatment duration were key limitations. In-person assessment was not conducted by dermatologists. CONCLUSION: Crisaborole improved signs and symptoms of SD and was well tolerated. Central reader assessment represents a promising approach for siteless clinical research.

The impact of radiofrequency ablation on quality of life/symptoms (VEINES-QOL/Sym questionnaire score) in patients with chronic venous insufficiency.

Purpose: Chronic venous insufficiency is defined as a progressive disease that impairs the quality of life. Symptomatic patients can be treated with a 97% success rate through endovenous radiofrequency ablation (RFA) procedures. The aim of this study is to evaluate the effect and impact of RFA therapy on both the Venous Insufficiency Epidemiological and Economic Study Quality of Life/Symptom Questionnaire (VEINES-QOL/Sym) scale and the VEINES-QOL/Sym severity score in patients with isolated vena saphena magna insufficiency. Methods: Between March and June 2018, a retrospective analysis was conducted on 45 patients with a healthy vena saphena parva. They were divided into two groups based on the diameter of the great saphenous vein (GSV). Patients with GSV < 6 mm were assigned to group I (n = 22, 15 males, 7 females, mean age 52.45 ± 13.98 years), while patients with GSV ≥ 6 mm were assigned to group II (n = 23, 14 males, 9 females, mean age 55.04 ± 10.18 years). The pre-procedural Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification and post-procedural quality of life and symptom assessment at 12-24 months were evaluated using the VEINES-QOL/Sym questionnaire scale. Results: When all patients were assessed in terms of the VEINES-QOL/Sym questionnaire scale, compared to the previous year, it was found that 57.8% of patients (n = 26) still experienced complaints, and 24.4% of patients (n = 14) reported slightly worse symptoms than the previous year. In group II, 56.5% of patients (n = 13) reported experiencing similar complaints as the previous year, while 30.4% (n = 7) noted slightly worse symptoms. Conclusions: Our study findings revealed that the increase in vessel diameter does not significantly impact the severity of symptoms and quality of life outcomes after RFA therapy; however, it does have a notable impact on the improvement of symptom characteristics. As a result, early intervention for symptomatic patients is crucial in order to address their symptoms and improve their quality of life.

Femoral vein stenting versus endovenectomy as adjuncts to iliofemoral venous stenting in extensive chronic iliofemoral venous obstruction.

PURPOSE: To compare femoral endovenectomy with the creation of an arteriovenous fistula (FE + AVF), versus iliofemoral endovenous stenting with the concurrent extended femoral vein (FV-S) stenting in patients with chronic iliofemoral venous obstruction (IFVO). MATERIALS AND METHODS: In a randomized prospective single-center study, 48 received (FV-S), while the other 54 had (FE + AVF). RESULTS: There were no statistically significant differences in the primary outcomes between the two groups (FV-S) and (FE + AVF) (59% vs 56.8%, 75% vs 79.1%, respectively). At a median of 13 months after the treatment. However, the FV-S group's patients experienced fewer postoperative problems (p = .012), shorter procedures (p = .001), and shorter stays in the hospital (p = .025). CONCLUSION: There is no difference between the efficacy and symptomatic resolution of the FV-S group and the FE + AVF group at the same time, FV-S has lower postoperative complications and a shorter procedure duration and hospital stay.

Endovenous glue ablation for chronic venous insufficiency: A comprehensive 5-year assessment of clinical and hemodynamic outcomes.

OBJECTIVES: Chronic venous insufficiency is mainly caused by reflux, obstruction, or both. Endovenous glue ablation has become one of the widely used methods for treating reflux in recent years. Duplex ultrasonography is the most commonly used method for diagnosing and evaluating treatment. However, there is important information that plethysmographic venous hemodynamics provides, which Duplex USG cannot provide. This retrospective study aimed to evaluate the 5-year clinical, anatomical, and hemodynamic results of endovenous glue ablation in the treatment of chronic venous insufficience, accompanied by the data from the plethysmographic study. PATIENTS AND METHOD: Between January 2018 and August 2018, 133 patients with symptomatic CEAP 2-6 varicose veins with reflux of the great saphenous vein lasting longer than 0.5 seconds and a diameter of 5.5 mm in the standing great saphenous vein underwent EVGA. CEAP, VCSS, CIVIQ 20, Doppler USG, GSV diameters and insufficiency times, and hemodynamically Venous Refilling Time and Venous Half-Value Time measurements were performed before the procedure. In the same way, measurements were made at the 1st, 3rd, 6th, 12th, 24th, and 60th months of the patients who were called and came to the postoperative follow-up. RESULTS: Procedural success was 100%, and complete occlusion was observed %93 after treatment, at the 60 month. The improvement in VCSS (from 4.4 ± 1.3 to 1.7 ± 0.9), CIVIQ20 (from 8.5 ± 3.1 to 4.7 ± 2.0), VRT (from 20.3 ± 5.0 to 131.1 ± 4.0), and TH (from 2.8 ± 0.3 to 2.4 ± 0.2) was significant (p < .001 was for all). CONCLUSION: Endovenous glue ablation is a preferred method for the treatment of great saphenous vein insufficiency due to its ease of use and the comfort it provides to patients, as well as its effectiveness and safety. In particular, it can be considered an effective method for improving venous hemodynamics and relieving associated symptoms.

The clinical and economic impact of chronic venous insufficiency-associated lymphedema and the prevalence of persistent edema after venous intervention.

OBJECTIVES: To determine the demographics, outcomes, and healthcare utilization of patients with chronic venous insufficiency-associated lymphedema (CVI-LED) and the prevalence of lymphedema-specific therapy use after venous intervention. METHODS: The IBM MarketScan Commercial and Medicare Claims Databases were examined for patients with CVI-LED. Patient demographics and the use of lymphedema-specific therapy before and after venous intervention were collected. RESULTS: Of 85,601 LED patients identified, 8,406 also had a diagnosis of CVI. In the CVI-LED group, 1051 underwent endovenous ablation or venous stent placement. The use of lymphedema-specific therapy before and after venous intervention was 52% and 39%, respectively (p < .05). The mean time of initiation of LED-specific therapy following venous intervention was 265 days after ablation and 347 days after stent placement. CONCLUSION: Treating venous hypertension improves certain venous-related signs and symptoms of CVI. However, a significant proportion of patients have persistent edema which may reflect underlying, sub-optimally treated LED.

Chronic venous insufficiency, could it be one of the missing pieces in the puzzle of treating pain?

Pain is a common complaint among patients seeking medical care. If left untreated, pain can become chronic, significantly affecting patients' quality of life. An accurate diagnosis of the underlying cause of pain is crucial for effective treatment. Chronic venous insufficiency (CVI) is frequently overlooked by pain physicians. Moreover, many pain physicians lack sufficient knowledge about CVI. CVI is a common condition resulting from malfunctioning or damaged valves in lower limb veins. Symptoms of CVI, ranging from mild to severe, include pain, heaviness, fatigue, itching, swelling, skin color changes, and ulcers in the lower limbs. Recently, it has become more widely known that these symptoms can be attributed to CVI. Even slight or mild CVI can cause related symptoms. Pain physicians primarily consider neuromusculoskeletal disorders when assessing patients with leg pain, and often neglect the possibility of CVI. In clinical practice, when pain physicians encounter patients with unresolved leg pain, they must assess whether the patients exhibit symptoms of CVI and conduct tests to differentiate CVI from other potential causes.

The anterior saphenous vein. Part 1. A position statement endorsed by the American Vein and Lymphatic Society, the American Venous Forum, and the International Union of Phlebology.

BACKGROUND: There is a lack of clarity regarding the terminology of the anterior accessory saphenous vein (AASV) that can impact treatment outcomes. Although use of the word "accessory" implies that the vein is a superficial tributary, evidence supports its role as a truncal vein, similar to the great and small saphenous veins, and warranting a change in terminology. METHODS: A multisocietal panel was convened by the American Vein and Lymphatic Society (AVLS), the Union International of Phlebology (UIP), and the American Venous Forum (AVF). The group was charged with reviewing the existing anatomic and clinical literature pertaining to the term "anterior accessory saphenous vein" and to consider the need for alternative terminology. CONCLUSION: Based on the insights gathered from the literature review and extensive discussions, the panel recommends changing the terminology such that the "anterior accessory saphenous vein" (AASV) now be designated the anterior saphenous vein (ASV).

Mechanochemical ablation: disappointing long-term anatomic results and worsening symptoms.

An updated report on the five-year results in the treatment of great saphenous vein incompetence with mechanochemical ablation (MOCA) provides additional evidence for higher rates of anatomic recanalization compared to other treatment modalities and progressive worsening of symptoms with time.
